Apparatus and method for learning gear ratio control of CVT

Abstract

An apparatus for learning gear ratio control of a CVT (Continuously Variable Transmission) may include: an APS (Acceleration Position Sensor) configured to detect a change of an accelerator pedal in a CVT vehicle; a gear ratio detector configured to detect a pulley gear ratio of the CVT; a timer configured to measure the time during which gear ratio control learning is performed during power-off up-shift of the CVT; and a controller configured to receive the values detected through the APS, the gear ratio detector and the timer, and control the CVT to shift gears at a target gear ratio learned through the gear ratio control learning, during the power-off up-shift by coasting.
